Glide 加载网络图片 - Android

1、权限

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

2、添加依赖

implementation 'com.github.bumptech.glide:glide:4.8.0'

3、加载网络图片

Glide.with(v).load(picUrl).placeholder(R.mipmap.ic_loading).error(R.mipmap.ic_load_failure).into(ivPic);

4、图片缓存

//禁止缓存
Glide.with(this).load(imageUrl).skipMemoryCache(true).into(imageView);
//清除缓存，必须在UI线程中调用
Glide.get(context).clearMemory();

//设置缓存
Glide.with(this).load(imageUrl).diskCacheStrategy(DiskCacheStrategy.ALL).into(imageView);
 DiskCacheStrategy.ALL：缓存源资源和转换后的资源
 DiskCacheStrategy.NONE：不作任何磁盘缓存
 DiskCacheStrategy.SOURCE：缓存源资源
 DiskCacheStrategy.RESULT：缓存转换后的资源

5、Cookies 设置

保存cookies

public class SaveCookiesInterceptor implements Interceptor {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Response originalResponse = chain.proceed(chain.request());
        if (!originalResponse.headers("Set-Cookie").isEmpty()) {
            HashSet<String> cookies = new HashSet<>();
            for (String header : originalResponse.headers("Set-Cookie")) {
                cookies.add(header);
            }
            UserKeeper.setCookies(cookies);
        }
        return originalResponse;
    }
}

设置 Cookies

HashSet<String> preferences = UserKeeper.getCookies();
LazyHeaders.Builder builder = new LazyHeaders.Builder();
for (String cookie : preferences) {
    builder.addHeader("Cookie", cookie);
}
GlideUrl cookie = new GlideUrl(url, builder.build());
Glide.with(context).load(cookie).apply(options).into(view);

6、Gilde 设置 Tag 报错问题

//清单文件中加入
<application
        android:name=".MyApplication"
......>
</application>

public class MyApplication extends Application {
    @Override public void onCreate() {
        super.onCreate();
        ViewTarget.setTagId(R.id.glide_tag);
    }
}

//创建资源文件：src/main/values/ids.xml
<resources>
    <item type="id" name="glide_tag" />
</resources>

7、混淆设置

##Glide
-dontwarn com.bumptech.glide.**
-keep class com.bumptech.glide.**{*;}
-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public class * extends com.bumptech.glide.AppGlideModule
-keep public enum com.bumptech.glide.load.resource.bitmap.ImageHeaderParser$** {
  **[] $VALUES;
  public *;
}
